Well, James, first, I didn't bother reading the thread you found offensive. They usually end in food-fights. I'm sure you know this.
Bob, I do have to respond to your attempt at comparison because your premise is based only on salaries, which falls short because it doesn't include the un-taxed subsidies accorded residents of different countries, different regions, cities, towns and villages.
I can speak only for France and give examples of a few benefits just off the top or my head: non-taxed subsidies are given to a huge percentage of families. When my first child was born 44 years ago, the postman knocked on the door one day and gave me three month's of subsidy in cash from the gov. health insurance. Today, it's direct deposit. All doctor visits, supplies before and after birth, hospital stay, everything was free. Transportation to the hospital for treatments is free. If a home aide is needed to clean your house while convalescing, the mayor's office pays it.
Employees' lunches are subsidized. Employers either run a cafeteria with full three-course meals, bread, wine, coffee, or if the company is smaller, the employees receive meal vouchers. You see the signs in the windows of restaurants, cafes, brasseries, bakeries announcing the brands of vouchers they accept. Vacations are subsidized, children's summer camps are subsidized, school supplies are subsidized. Treatment for cancer and many other diseases is covered 100%, including transportation to and from the treatment hospital or center.
Childcare centers run by the localities are subsidized, though hard to get a slot. My children's had a full time cook who even made the yogurt. Otherwise, childcare is subsidized. Public school begins at age 3--free--all day. Once in a while a 2.5 year old can start.
Where I live, bus and tram transportation is free for under 18 and over 65 years of age but it will soon be extended to all residents.
Every child learns to swim as part of the public school curriculum.
Some elementary classes go to the Alps for a month, staying in a hostel built for such a purpose, with school work in classrooms downstairs half the day and skiing the other. It's free. Clothes for the classe de neige are handed down from family to family through the mayor's office. Not all classes go; the teacher has to request it.
Many organizations (student groups, residents of towns, sister city programs) have subsidized low-cost ski vacations, travel to other countries, travel within France at a fraction of the cost on the open market. There are nature centers, hostels, etc that run year-round for discounted group travel, student, adult, senior citizens organizations.
So while you took a stab at comparing, you would really need to delve much further into the benefits and discounts received to be able to accurately compare salaries and actual standards of living.
